A gas giant located about 260 light-years from here has winds that howl at the speed of sound and a day side that's hot enough to melt iron. We know this because astronomers have just made the most detailed weather map of the temperature of an exoplanet's atmosphere. Here's the forecast for WASP-43b. »10/10/14 12:40pm 10/10/14 12:40pm

There's a gas giant located about 330 light-years from here that's not only unusually large, it's also orbiting its host star at an incredibly close distance. According to a new study, this combination of factors is wreaking havoc on the star's innards.»9/17/14 12:40pm 9/17/14 12:40pm

Prior to the discovery of exoplanets, astronomers assumed that our solar system's configuration was typical. But now, some 1,715 exoplanets later, we know that we're far from ordinary. So what passes for "normal" in the annals of solar systems? Here's what we know now. »4/28/14 12:00pm 4/28/14 12:00pm

They’re big, full of gas, and have a penchant for hanging out way too close to their parents. These “hot Jupiters” are among the most common extrasolar planets in the galaxy. Here’s what the latest science is telling us about these celestial wonders. »8/21/13 10:09am 8/21/13 10:09am

An emerging branch of science known as exometeorology is offering remarkable insights into the conditions found on some of the more extreme planets in the galaxy — including the weird and mind-boggingly massive weather patterns experienced on a hot Jupiter that's 385 light years from Earth. »5/27/13 12:00pm 5/27/13 12:00pm
